Specification of Letters Patent.

Application filed May 24, 1916. Serial No. 99,663.

To all whom it may concern:

Be it known that I, LOUIS W. WITRY, a citizen of the, United States of America, and a resident of Waterloo, Blaekhgnvlc county, Iowa, have invented certain new and use iul Improvements in Implement-Shifting Means for Tractors, of which'the following is a specification.

My invention relates to improvements in plow shifting mechanism for traetors,and th'e object of my improvement is to supply for tractors or other like se lfipropelled vehicles or any propelling means, a device capable of employment for horizontally shift ing the .plow or other implement attached thereto transversely-relative to the line of direction thereof.

This object I have accomplished by the means which arehereinafter described and claimed, and which are illustrated in the accompanying drawings, in which: v

Figure 1 is a detail view of my improved shiftmg'means as operatively connected between the rear part only of the frame of a tractor, and a plow drawn thereby.

Fig. 2 isan enlarged rear elevation of the rack-segment of said invention, with shifting-lever connected thereto, and broken Fig. 3 15 a side elevation of said rackse ment and lever.

imilar numerals of reference denote corresponding parts"throughout the several views.

Referring to Fig. 1, the rear part of the frame only of a tractor is shown, comprising the side-beams 16 with connections, rear platform with anglebar 17 mounted thereon, and a medially depressed cross-bar 15 connecting the two side-beams 16. A horizontally swinging bar 13 has its front end orificed as is also the cross-bar 15 to both receive a pivot-bolt 14, the bar 13 extending rearwardly beyond the platform and its angle-bar 17.

1 On the ang-leyhar 17 isfixed a rack seg ,nlcnt 1, having a plurality of radial rooves (L. Thoracic-segment is centrally ori ced to seat a pivotin, or-bolt 2 extending rearwardly there rom tofserve as a pintle for the erated shiftingdever 7,-the lat manually 0 r apt'ed' to seat tself in either of ter being a compulsion of the spring.

the grooves 6, when first pushed outwardly against the coiled compression-spring 8 mounted about the pin .2 and secured there on by nuts 3 and 1, and then released to be held releasably secured in the groove by the T e lower end of the lever slides over a semi-circular boss 5 on the raclcsegznentso that the spring works only on the upper half of the lever to'keep it sprung into a notch of the racksegment. The rear end of the bar 13 is orifieed, and a connecting-rod 10' is also orifiecd, the two being pivot-ally connected by a bolt 12, while the other end of the rod 10 is pivotally connected to the lower end of the lever 7 adjustably by a bolt 9, inserted in one 01? the orifices 11 in said rod.

By another bolt 18, the orificed head 19 of a bea'm'20, carrying a plow share 21,01

any, other implement,-may be detaehablyconnected. to the rear end of the bar 13.

The hand -lever 7 may be shifted to shift the bar 13 swingingly from side to side horizontally, to likewise shift the implement 21 laterall The device may be applied to any form of tractor or other propelling means, and to gangs of "plows or other implements drawn thereby.

Having described my invention, whatl claim as new, and desire to secure by Letters Patent, is:

Implement shiftingri'neans, comprising a laterally-swinging (lltlfi' COIlllGClllOll pivoted to the frame of a tractor or the like, a radi- .-.1lly-notched rack-segment mounted on said frame, a lever pivoted on said segment and.

adaptcd'to enter any of said notches, a semi oircu la r boss on said segment, concentric with sald notches, and below the pivotal conto exercise a yielding pressure upon the lever to hold the upper part thereof in any notch of the rack-se me'nt.

Signed at aterloo, Iowa, this 8th day of May, 1916. I
